Instead of hardcoding it. Excluded from the repository via .gitignore. Also adding TestData to the project, compiled into the Test bundle.
Pushing the iOS deployment target down to 4.3, and ensuring that all projects have the same value there.
testSentDate wasn't quite passing: sentDateGMT has been removed and the number of seconds representing the date the email was sent is not what was there before. Fixed.
Also, we needed to pull the message files out of the test bundle.
